One of the central tasks in retinal neuroscience is to understand the circuitry of retinal neurons and how those connections are responsible for shaping the signals transmitted to the brain. Photons are detected in the retina by rod and cone photoreceptors, which convert that energy into an electrical signal, transmitting it to other retinal neurons, where it is processed and communicated to ce...
abstract the prediction of active earth pressures is essential to the design of retaining walls in case of reinforced and unreinforced soils. in this study, a new analytical method is presented to determine the coefficient of earth pressure. the horizontal slice method is used to compute the active earth pressure behind a rigid retaining wall in consideration of the granular soils. to verify th...
OBJECTIVES When analysing the 3D structure of tissue, serial sectioning and staining of the resulting slices is sometimes the preferred option. This leads to severe registration problems. In this paper, a method for automatic registration and error detection of slices using landmark needles has been developed. A cost function takes some parameters from the current state of the problem to be sol...
We propose an obstacle detection method based on trinocular stereo vision which consist of vertical and horizontal stereo cameras. Vertical edges and horizontal edges are extracted from horizontal stereo images and vertical stereo images. Then the edges are used to generate U-V-disparity maps. A rectangular obstacle has a characteristic that it is represented as a vertical line in V-disparity m...
One of the most crucial techniques associated with Computer Vision is technology that deals with the automatic estimation of gaze orientation. In this paper, a method is proposed to estimate horizontal gaze orientation from a monocular camera image using the parameters of Active Appearance Models (AAM) selected based on several model selection methods. The proposed method can estimate horizonta...
A model-based approach to interactive segmentation of abdominal aortic aneurysms from CTA data is presented. After manual delineation of the aneurysm sac in the first slice, the method automatically detects the contour in subsequent slices, using the result from the previous slice as a reference. If an obtained contour is not sufficiently accurate, the user can intervene and provide an addition...
The upper structure of high piled wharf in coastal soft soil area is loaded by waves or ships, which transferred to the foundation through pile foundation. force small and lasts for a long time, causes strength saturated clay vibration range decrease slowly, weakening effect gradually accumulates, resulting horizontal displacement In this paper, maximum residual are deduced calculated analytica...
